Then how about:
    try:
        s = ... # socket opens
        try:
            # various code ...
        finally:
            s.close() # socket closes
    except socket.error, x:
        # exception handling

This handles all the socket exceptions in one shot. The only problem is
that different problems may have to be handled differently. For instance,
you may need to handle a transmission that failed in the middle differently
than a failure to open the socket.
